Note that since OpenStreetMap changed the licensing scheme for its database, the CC BY-SA license is no longer compatible for data imports in OSM: data previously published under CC BY-SA must be relicensed to another suitable and compatible license (such as CC-BY or CC0) to be usable in OSM, or specific permission by legitimate owners of the original work must be granted to use them in OSM under ODbL (with the appropriate attributions when necessary).

However maps rendered from OSM Data may be licensed with CC BY-SA, and the content of this OSM wiki is still licensed under CC BY-SA. If you publish data on this wiki, this data will not be reimportable to the OSM Database by others, unless you import them yourself or explicitly provide an additional licence for such imports.
